Kafka has become a critical part of most large scale distributed infrastructures. We provide it as a self-service tool where topics are first class citizens. Due to its nature, Kafka is used as a connector between projects of different teams. This presents operations, multi-tenancy, and security challenges in providing a managed service to large organizations. In this talk we will present how we built infrastructure that enables teams to use Kafka while keeping things secure, flexible and maintaining low operational overhead. We’ll talk about our data model, cluster discovery, end-to-end asymmetric encryption framework, and identity management.
